I have a simple problem which (to me) seems to be difficult to solve in ArcGIS. The map I plot is a GeoTIFF with emission data. I use a default algorithmic color ramp (rainbow) to do so. Now I would like to replace the lowest value (=0.0) with white instead of blue.
The only solution I have come up with yet is to create a new Mulltipart color ramp with the first part being preset and the second algorithmic. This way, the color steps in the first part are much coarser than in the second one. Is there a way to reduce the number of colors in the preset color ramp to 1?
Any help is really appreciated - thanks!
